The Gravity 4.0 helmet delivers downhill-certified protection in a lightweight, breathable package—ideal for enduro racers, park laps, and e-MTB missions. The in-moulded dual-density EPS + EPO impact foam works with Leatt’s 360° Turbine Technology to protect against low-speed impacts, high-speed impacts, and rotational forces, forming a 3-in-1 safety system you can count on when the trail gets technical.
A removable mouthpiece cover lets you customize airflow, while 22 vents keep the air moving even at lower speeds. The Dri-Lex® liner is moisture wicking, breathable, and washable for long-ride comfort, and the Fidlock magnetic buckle makes on and off fast and easy. With DH certification, neck brace compatibility, and a great price, the Gravity 4.0 delivers dependable protection when racing against the clock.
3-In-1 Safety System
When combined with the impact foam, 360° Turbine Technology offers a unique 3-in-1 safety system by protecting against low-speed impacts, high-speed impacts, and rotational forces.
Impact Foam
Dual density, in-moulded EPS + EPO impact foam for superior energy absorption.
Rotation protection
The optimally designed turbine discs enable the helmet to move slightly on the head upon impact, helping to reduce peak acceleration to the head & brain.
Low-impact protection
The special energy-absorbing material in the turbines absorbs low-impact energy associated with concussion.
